ABSTRACT
The conversion of municipal solid waste (MSW) to refuse-derived fuel (RDF) is an alternative energy recovery option. Biodrying is one of the techniques that can remove moisture from wastes at a low cost and increase the energy content of RDF. It relies on microbial activities that generate heat from the aerobic decomposition of organic wastes to evaporate water from the waste matrix. This chapter presents information on biodrying technology with its application to MSW containing high moisture content that is commonly found in Asian countries to achieve the required RDF standard for industrial utilization. First, different types of mechanical biological treatment of MSW were introduced with their applications and potential challenges. The fundamental of the biodrying process, influencing factors, and appropriate conditions are described. Laboratory and larger scale applications of biodrying technology in Thailand are demonstrated.
